This is a Proprietary Laboratory Analyses (PLA) code, meaning that the code applies to only one unique lab test made by a specific manufacturer or performed by a specific lab. Report 0172U for the myChoice® CDx test from Myriad Genetics Laboratories, which determines homologous recombination deficiency (HRD) status using somatic mutation analysis to detect variants in tumor suppressor genes BRCA1 and BRCA2. The test uses DNA from formalin–fixed paraffin–embedded tissues of solid organ tumors. The resulting genomic instability score provides an algorithmic measurement of certain biomarkers valuable for selection of ovarian cancer treatment.
